| Abstract: |
An innovative towed active sonar concept is proposed which significantly reduces peak and average input power. The system also reduces radiated acoustic source level by approximately 10 dB over previous systems designed for similar applications. The reductions are attained by distribution of source energy in time and space. Transmitter waveform and search schemes are proposed as well as a source-receiver interference reduction strategy. A detection performance metric is proposed for use in comparing alternative system concepts or parameters. Application of the metric indicates a potential detection gain of 12 dB using the proposed technique. |
| Benefits: |
The proposed concepts are expected to provide significant improvement to active sonar performance with major reductions in radiated source level that has been a recent environmental concern. The concepts are expected to lead to design simplifications for active sonars and major reliability improvements for power train components, which are driven by peak power levels. The proposed concepts can also lead to reduction in the size and weight of sonar transmitters and, in some cases, placement in more convenient installation locations. |
